3+5.2x=1-2.8x

1. 3+5.2x+2.8x=1

2. 5.2x+2.8x=1-3

5.2x+2.8x=1-3

1. 8x=1-3

2. 8x=-2

8x=-2

1. =-(1/4)

Alternative form:

2. x=-0.25

Which expression is equivalent to (4 + 7i)(3 + 4i)? –16 + 37i 12 – 28i 16 – 37i 37 + 16i
ASHA 777 [7]

Answer:

The equivalent expression is \Rightarrow -16+37i    

A is correct

Step-by-step explanation:

 We are given two complex number and need to multiply it. To find equivalent fraction.

(4+7i)(3+4i)

Using Binomial product property: (a+b)(c+d)=ab+ad+bc+bd

\Rightarrow (4+7i)(3+4i)

\Rightarrow 4(3)+4(4i)+7i(3)+7i(4i)

\Rightarrow 12+16i+21i+28i^2

Combine the like term and simplify

\Rightarrow 12-28+37i           \because \ \ i^2=-1

\Rightarrow -16+37i    

Hence, The equivalent expression is \Rightarrow -16+37i
